依据地球化学景观条件和采样介质的不同， 有针对性地选用顺序相态提取分析技术，对亚热带湿润－ 半湿润低山丘陵景观区和亚热带岩溶景观区内两个卡林型金矿区的表生地球化学异常特征进行了研究， 分析了景观条件、表生作用等因素对金在表生介质中的存在形式、含量变化、异常元素组合及在土壤中富集层位的影响， 探讨了导致这两类不同景观区中金的表生地球化学异常特征存在差异的原因， 并在此基础上讨论了这两类不同景观研究区中制约金的表生地球化学异常发育的重要因素。
According to the difference of geochemical landscape conditions and sampling media, the sequential phase extraction technique was used to analyze the table of two Carlin-type gold mining areas in subtropical humid-subhumid hilly landscape area and subtropical karst landscape area Geochemical anomalies were studied. The effects of landscape conditions, epigenetic effects and other factors on the existing forms and contents of gold in superficial media, the composition of anomalous elements and the enrichment of layers in the soil were analyzed. The differences of the epiphytic geochemical anomalies of gold in these two types of landscape areas are discussed. Based on these, the important factors of the epiphytic geochemical anomalies in the two different landscape areas are discussed.
